The invention provided a heatsink thermal module with noise improvement, which has a heatsink thermal module additionally consisting of a heat pipe, a heatsink fins set and a fan module; the fan module is combined with the heatsink fins set which consists of multiple heatsink fins with different lengths and is combined to the fan module with its end with a special geometric shape having the function of lowering the wind drag; by lowering the wind drag, not only the heat dissipation efficiency can be increased, but the noise caused by the heatsink thermal module can also be improved.
